We divide 397085 by 1
The aim is to understand the frequency of 1 in 397085.

Advancing to step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Let's proceed to step 2:
When dividing 9 by 1, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 0 after subtracting 9 from 9.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Going ahead to step 3:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 397.0
Deduct 7 from 7 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Let's proceed to step 4:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3970.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Advancing to step 5:
8 divided by 1 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 39708.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Step 6:
When dividing 5 by 1, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 397085.0
The remainder is 0 after subtracting 5 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 397085.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 397085.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 397085.0 and a remainder of 0.0.
